Multi-Size Compatibility: Fits perfectly into 40mm (1 1/2″) waste pipes to accept smaller 19mm, 21.5mm, or 23mm overflow pipes.
Tool-Free Installation: Simple push-fit design requires no solvent cement or specialized tools for a watertight seal.
Vibration Dampening: Durable rubber construction absorbs system vibrations and allows for slight pipe thermal expansion.

A 40mm rubber waste adaptor (often called a “rubber bung” or “socket reducer”) is a versatile plumbing fitting used to connect small-diameter pipes into larger waste systems. It is most commonly used to terminate a 21.5mm overflow pipe or a boiler condensate discharge line into a standard 40mm kitchen or bathroom waste pipe.
While solvent weld fittings create a permanent chemical bond, a rubber waste adaptor offers the advantage of flexibility and easy maintenance. In situations where pipes may need to be disconnected for cleaning or where the two pipes being joined are made of different materials (such as plastic to copper), a rubber adaptor provides a reliable friction seal that can be installed or removed in seconds. It is the ideal “fit-and-forget” solution for tight spots under sinks or behind appliances.
At ECO HEAT SHOP, we ensure our rubber adaptors are manufactured from high-density, synthetic rubber. This material is resistant to common household chemicals, detergents, and the temperature fluctuations found in domestic drainage. The tapered “ribbed” exterior ensures a snug fit into the 40mm socket, preventing “weeping” leaks even under the constant flow of a condensing boiler or a faulty cistern overflow.
